Sites for Gamma-ray Astronomy in Argentina
A. C. Rovero, G. E. Romero, I. Allekotte +9
We have searched for possible sites in Argentina for the installation of large air Cherenkov telescope arrays and water Cherenkov systems. At present seven candidates are identifie…
Implications of the VHE Gamma-Ray Detection of the Quasar 3C279
Markus Boettcher, Anita Reimer, Alan P. Marscher
The MAGIC collaboration recently reported the detection of the quasar 3C279 at > 100 GeV gamma-ray energies. Here we present simultaneous optical (BVRI) and X-ray (RXTE PCA) data f…
H.E.S.S. Observations of the Prompt and Afterglow Phases of GRB 060602B
HESS Collaboration, F. Aharonian
We report on the first completely simultaneous observation of a gamma-ray burst (GRB) using an array of Imaging Atmospheric Cherenkov Telescopes which is sensitive to photons in th…
Search for Gamma-rays from Dark Matter annihilations around Intermediate Mass Black Holes with the H.E.S.S. experiment
HESS Collaboration, F Aharonian, G. Bertone
The H.E.S.S. array of Cherenkov telescopes has performed, from 2004 to 2007, a survey of the inner Galactic plane at photon energies above 100 GeV. About 400 hours of data have bee…
Suzaku observation of TeV blazar the 1ES 1218+304: clues on particle acceleration in an extreme TeV blazar
R. Sato, J. Kataoka, T. Takahashi +3
We observed the TeV blazar 1ES 1218+304 with the X-ray astronomy satellite Suzaku in May 2006. At the beginning of the two-day continuous observation, we detected a large flare in…
Discovery of VHE gamma-rays from the high-frequency-peaked BL Lac object RGB J0152+017
HESS Collaboration, F. Aharonian
Aims: The BL Lac object RGB J0152+017 (z=0.080) was predicted to be a very high-energy (VHE; > 100 GeV) gamma-ray source, due to its high X-ray and radio fluxes. Our aim is to unde…
